01 - Preheat the oven to 350°F. Grease and line an 8x8-inch baking pan with parchment paper.
02 - In a large mixing bowl, whisk together melted butter, granulated sugar, and strawberry puree until thoroughly blended.
03 - Add eggs and vanilla extract to the bowl. Mix until the batter is smooth and well combined.
04 - In a separate bowl, whisk together all-purpose flour, baking powder, and salt.
05 - Gently fold the dry ingredients into the wet mixture until just incorporated. Avoid over-mixing.
06 - Pour the batter into the prepared pan. Smooth the surface with a spatula.
07 - Place the pan in the oven. Bake for 22 to 25 minutes or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs.
08 - Remove the pan from the oven and let the brownies cool completely in the pan.
09 - In a bowl, whisk together powdered sugar, strawberry puree, and lemon juice until the glaze is smooth and pourable.
10 - Spread the glaze evenly over cooled brownies. Allow the glaze to set for 15 minutes, then cut into squares and serve.
